Welcome to the forum! i suggest you do a search on myHD AND hipix as this has been asked several times before. you might need to specify titles only to limit the number of responses to only those that have asked this question.
Both are about the same when it comes to scheduling recordings. Neither has anything over Tivo when it comes to the ability to automatically change your schedule recordings. In fact if one of your scheduled recording changes time or moves to another day the MyHD/HiPix card will still record the original time/day that you specified. I personally think the HiPix card has better software support but it seems the card is getting harder to find.
